the features of the circu of the patent issued to me October 15, 1907, No. 868,276.

This patcntcd machine is adapted to produce flat knitted goods, ribbed goods. tubular fabrics, welts and pattern goods, and comprises a cylindrical needle bed and a horizontal or disk needle bed each having two groups of needles arranged with narrow spaces between them, two sets of cams and two ca'mcarriers for the cylinder needle bed and for the disks needle bed; means for rotating the cam carriers of each of the needle beds in opposite directions, the cams being caused to act alternately on the two groups of needles of each of the sets of needles and the needles being provided with two butts, a yarn carrier for each group of needles a-lternately moved by the cam carriers to act in presenting the yarn to the needles in uni son with the cams. It also includes means for racking the needles to produce pattern fabrics, &c. This machine is thus adapted to simultaneously produce two articlesor pieces'of knitted fabrie with theleast possible loss of time due to intervals when the cams. are'necessarily inactive, that is at the time they are passing by the narrow spaces between the two groups of needles of each set' to act alternately on the needles of each group.

This ring by under brackets 27 5 supports 'the cylinder needle bed 25 and also by a bracket and central stem 29 1t supoorts the upper or disk needle bed 30. Ex-

tending from the ring 26 are standards 31 curved inwardly at their upper ends and to 10 which is secured a ring 32 having guide-Ways on its inner and outer sides upon which travel the thread carriers and also cam ledges for controlling certain parts ofthe vmachine. 16 The cam carriers for both the cylmder needle bed' and the disk needle bed are rotated in opposite directions by suitable gearin -here shown as a drive shaft 33, with n pu ley 34 and stop drive 35, a inion 36 on .20 shaft 33 meshing into a gear 3 carried on a shaft having its bearing in the standard 38.

In general the construction and. mode of operation of the machine is as follows. The needles of the cylinder bed and horizontal bed are divided into two groups with blank spaces "or gaps between the 5- groups of needles. All of the needles have two butts; and cam carriers with suitable cams are providedto'act on thebutts,-that there are two cam carricrsfor each of the needle beds operated to actuate succes- 0 sively the needles 0 bed. lower butts of the cylindrical bedneedles and the-inner butts of the horizontal bed needles rotate in one direction; and the other 5 two carriers, acting on the upper butts of the cylinder bed needles and the outer butts of the horizoxtal bed needles respectively, rotate in the pposite direction, Suitable thread layersare provided adapted to recippair of groups of needles, and cam carriers rotating in opposite directions' control means for alternately reci roeating the thread layers. Thus the mac ine produces two articles simultaneously and lays two courses oi stitches in each article forever-y emnplete revolution of the machine. As this invention relates solely to .means for :uitormitically controlling the needle cams, whereby completed. articles so may be madewith various kinds of knitting stitches in different parts ofthem, means for automitically racking the needles and means for laying a. separating thread be.- tween{ the .articles as they are connectedly t5 continuously formed, it Is thought unnec- On gear 37 is a bevel wheel 39 which- -This vertical shaft and sleeve acfithe two groups, of each.

wheel 72 and also the ratchet essary to cin'nber up this case with more drawings and description of the main parts of the. machine, as these special devices of this invention may be used in other machines than the one described in sald patin the knitting art.

The essential features of'-th1s invention will be fully des'cribed by reference hadto the accompanying detail drawings.

The direct means for setting the needle cams are actuated through the medium of vertically sliding bars 44 and 45, and the primary means are pattern chains 46 and 47 acting through mechanism hereafter described to rcclprocate respectively the bars 44 and l5.

The needle racking is accomplished by means of cam's48 and 49 oscillated by suitable mechanism hereafter described controlled by pattern chain 50.

To avoid the necessity of making the chains 46, ,47 and 50 inconveniently long, as they control the formation of the articles throughout the length of a garment being made, they are intermittently actuated by a chain 51, Fig. 21.

The separating thread controlling mechanism is also controlled by the vertical bar 44.

' BarsJM, 45 are fitted to slide in bearing blocks 52, "53 and. 54, carried by one of the curved standards 31 of the frame, said also provided with guide bearblocks bei'n lugs-in wlnch slide horizontal bars. 55, 56,

57, 58, and 59. The inner ends of the bars .55, 56 areguided in block 60 extending from the inner upper end of said. standard =31. The lower ends of the bars 44, 45 are by links 61, 62 connected'to the ends of levers 63 and 64 respectively. These leversrock projecting from the standard 25 of the frame, and are provided mediatetheir ends with operating rollers-66 and 67. Extending from the standard 25 are two studs .68, and 69 carrying at their outerends- V which has at its 119-, p01 angle an inwardly extending stud'71. On he stud 68 is a sleeve carrying a ratchet '1 I s rocket Wheels 73, 74- and-75' on which hang he attern chains 46, 7 and 50 respectively, an on the stud $9.,is

a sleeve carrying a rat 'het 76. and' thje sprocket wheel 211 on which hangs the chain 51,; and also another sprocket wheel on Wlllbfll chain 50 may be placed, as hereafter desct lbed.

Referring to Figs. 17, 18,19 and 19, 88 indicates a rotating cam carrier for the cylinder needle bed of the machine; it is attached to and caused to travel with a ring 89 (see Fig. 3) which is Continuously rorated. I would here mention that there are two sets of cams for each of the two sets of needles, the needles of each set being divided,

into two groups, to provide for making .simultaneoustv two articles onthe machine;

'tioncd patent, and I would here call attenion to the fact that this statement applies to the cams, &c.', for operating inner butts of the horizontal needles. In this case, however, referring to thefhorizo ntal needles, the cams apd their actuating devices as illustrated inv thejdrawings are adapted to con trol the. needles by their outer butts. The cam 90 is set out in active position when the separating thread is'laid, shown in Fig.

position Withinthe-face ofthe carrier '88. \Vhen the can'isis inactive position it engages the lower butts'of the needles and operates the needles to my a-course of the separating thread betweenjtwo courses of the regular knitting. A stem 91 extends from the cam 90 through the outer wall of the carrier. On it withinthe carrier is a spring 92 which forees'the'cam outwardly, and on its outer end is secured a clutch shaped device 93 with cam shaped teeth which comet with corre;

sponding shaped. teeth extending from the face of a ratchet wheel 94, fitted to rotate on the stem 91. This ratchet is actuatedby a pawl 95 carried on bar96 slidalily held on -llie cam carrierby screws 97, in slots in the bar. Projecting from this bar is a-forked extension 98 in which works a roller or stud 9U carried by a lever 100, andthis lever-is pivoted at 1.01 to a bracket on the cam car rier. I The other end of this-lever is provided with a roller 102, which, as the carrier-ro tatcs, indirection indicated by the arrow, comes in contact with the end of the hori-- zontal bar 59 and so causes the ratchet wheel.

9% to move one teeth as the roller passes over the end of the bar; this movement of the resting on the high parts of the cam teeth of the ratchet and so withdraw-s the needle cam 90and holds it out of action until the bar 59 1s aga1n-pro ected into the path of travel of the roller 102; "then the ratchet- 94. is again.

moved one tooth and the cam closes into 'thecam teeth of the ratchet and the cam 90 moved out by the spring 9:2, as shown in full lines in Fig Q18. The parts of this device are 'set .in operative position by the spring 251 which acts on bar 96. The horizontal bar 59 is moved hack and forth as the bar 44. isnioved vertically through the medium of wedge blocks 101-5 and 104. attached to the bar 14 and working in a slot in l he bar 59 having counteracting inclined edges 105 and 100respcctivcly; the arrangement being such that as the bar 14: is moved upwardly the bar 59 is set with its end in the path of. travel of the rdlle 102-, and when it moves- (.lmvnwardly the bar 59 is withdrawn and held away from the "roller, as said roller passes by it. Similar wedge acting devices operate all 'of the other horizontal bars 55, 56, 57 and 58 and are similarly marked.

The vertical banal is actuated, as before described, by the patternehain lti which has some ofthe links formed with cum surfaces 107 and 108 of difi'erent heights, Fig. 20; these act on a roller 109 carried by a lever 110 which rocks on the stud 71. and this lever by its upper face acts on the roller (36 of the lever 03, which is connected to the vertical bar 44 by the link 61. The downward position of the-bar 44 is determined by l a pin 11'1 projecting from the frame of the machine under the lever 63. I The lever 6 is raised when theroller 109 of the lever 110 is acted .upon by the cam links 108. The

elfect of the rocking of the lever 110 as its roller is acted upon by the cam links 107 and ments of the-lever 110 tllO,l(Z\-'0l' 63 is not affected as it restson the pin 111. The cam is out in operative position when'the separating thread"v is being laid in one course of stitches madeby cylinder bed needles and one course made by the horizontal oredial bed needles- The other needlecams carried by the cylindvr cam carrier 88, shown in Figs. 17 and 18 but more clearly in plan View in Fig. 19, comprise a triangular cant-112 and .an elongated czup {113, said elongated cam being provided with a latch piece 114 pivoted mt 1171', adaplcd when depressed to. lie within and form a continuation o.f -,the upper straight edge of the cam and when raised to act as a riser for the needles.

lar up and d wn direction. hen it is in downward position the. latch 114 is also down and then the needles retain the loops The triangu- I -lar cam 11.2 is also fitted to Sll(l( in an angu when the second foluse lowing row of stitches are being laid, thus causing two adjoining stitches to be 'elon gated each to extend over two courses of stitc zesi The effect on the yarn when the cam 112 is in upper" position is to reduce the to act on a ratchet w eel 120 securedto the shaft 118. A spring 121 sets the arm 117' back in position to be acted upon by the bar 58 .af.ter it has been moved by the'same; 122 designates an angularly arranged shdehe'ld in a bearing 123 secured to the cam carrier 88, and this slide carries an adjustable block 125 secure 0 shaft 118 and having one- -half as many risersas there are-teeth 1n the ratchet 120. A stud 126 extends from the 124, with a dpointedend acted uponby a cam slide 122 through the carrier and has se-' curedtoits end aplate 127'fitted to'slide in a slot in the carrier, arranged at the same angle as the bearing of slide 122. Cam 112 isFsecured to the plate 127, it thereby being moved in" an angular directionand held up by'theslide 122 when one of the high points of the cam 12'5;acts on the block 124 of the slide 122; A spring 128 attached to stud 126 and the cam carrier draws the cam 112 into its lower position when the cam 125 is moved to allow the point of the block 124 to enter .one .of its depressions. The latch 114- of cam 113 is moved simultaneously with the cain112, that is the cam-and latch are moved up and down at the same time. A lever 129 and thislcvcr has a bearing face 136 which acts on the roller 67 'of the lever 64, whose end is'by a link 62 connected to the lower end of the bar 45. Rover 64 rests on the pin 111 when the rollert 134 falls off the cam link 133. i

The needles of the upper or horizontal bed 30, as before stated, are automatically controlled by their outer butts by cams on' the outer circular cam carrier 137, as shown in Fi 8 to 15. The cams 138, 139 and 140 with its latch 141 are arranged and actuated similarly 'in all essentialfeatures to the cams 90, 112 and 113 with its latch 114 of the needles of thecylinderbed before described. These cams 138, 139 and 140 are for convenience of manufacture and ad just-merit carried by a frame 142 held by screws 143 in the cam carrier 137. The cams are shown in different views for convenience of illustration, for instance the cam 138 and its operating mechanism are illustrated in Figs. 13 to 15 and the cams 139, 140 are illustrated in Figs. 8 to 12. To simplify description and facilitate comparison with the devices shown in Figs. 17 to 19 similar indicating numbers will be uscdwith an e pQnent a; earn 138 is pressed outlocatedinside of and pivoted at 130 to the cam carrier 88 is, by. a projection on its side, actuated bya cam 131 secured tothe shaft 118 said cam is similar to cam125; the end of. the lever acts on a pin' 132 extending from the latch 11 4 throu h a cireula-r'slot in the inner wall of the carrier 88, in such manner -that when the lever is re'stmg on one wardly to act on the needles by a spring 92 surrounding a stud 91 extending from the cam through the circular carrier 137. A clutch shaped cam 93 is secured toupper end of the stud and its counterpart is attached to or forms part of a ratchet wheel 94. In this case the ratchet wheel 94 is acted upon by. a pawl 144 carried on the end of a flat circular bar 145 located on and held in position by screws 146, in slots formed in the bar, on thecircular' cam carrier' 137. This bar 145 extends about half wayround the 'carrier'and to its end diametrically opposite the 'pawl end is, secured a short standard 147, to which is connected one end of a link 148, whose other end is pivoted to the lower end of a lever 149. This lever rocks on .a stud 150 extending. from a bracket standard 151 secured to andprojecting upof therisers of the cam 131 the latch is held a in upper or outer position, and from this POSitlOIllt is depressed by t e actio'n ofthe needlesthereon, so as to'aiford a straight path for the butts of the necdles'overthe Iupgeredge oi cam '1I3,when the cams'125 131' are moved for their coacting arts to enter low parts 01f-d eprcssions" the cams. i 1 f5 1 i 6 The horizontal sliding bar-.58, which-actuates the devices just described .is moved-by the vertical bar 45, and "this bar is raised by cam links 133 carried by the chain 47, see Fi v g. 21. The cam links act on roller 05- 134 of a lover 135 rocking on the stud 71,

wardly from the cam carrier 137. The upper end oflever 149 is provided with a roller 152, which is in the path of and strikes against the end of the horizontal'bar '55,

when said bar is set in active position by theupward movementofthe vertical bar 44 which is controlled by the pattern chain 46, as before described. The action of the bar '55 on the roller "152 is to movethe lever as shown by dotted lines in Fig.16 and cause; the pawl to feed the ratchet wheel 94 one Q-i tooth. AA spring 153 rnovesthe bar back and sets the lever 149 into position shownf. by full lines "in .Figs. 13 .to 16- when the when 152 moves ofi -the end of bar 5510s the cam carrier is rotated. The operation of these parts occurs) when the separating thread-is to be laidin-a coursefof stitches formedby the horizontal set, of needles. Referring to Figs. 10, 11 and 12 the sliding cam 139 is connected by stud 126 to the slide 122, actuated by the cam 125, which, is secured to the shaft 118". The operating ratchet wheel 120 and another cam 131arc also-secured to shaft'118". The cam 131 acts on the lever 129 which raises the latch 141 of the cam 140 by acting on the pin 132. The functions and operation of these devices are -similar to the corresponding devices carried, by the c linder cam carrier 88. A pawl 154 carrie 'at one end of a flat circular bar 155 act-mates the ratchet wheel 5 120. Said bar extends around the cam carrier opposite the circular bar 1 15,- and is attached to, the carrier 1137 by sliding connections, consisting of screws 156 passing through slots in the bar. To the other end 0 of the bar 155 is attached a short standard 157, which, by a link 158 is connected to the lower end of a lever 159, rockin on the stud 150 alongside 'the lever 149. t the upper end of the lever 159 is a roller 160, which by striking the end of the horizontal bar 56 causes lever to move into position shown by dotted. lines, Fig. 9, and the pawl 154 to partly rotate the ratchet wheel 120*. A spring 161 acts on bar 155 to setthe lever ac 159 back when the roller 16.0 leaves the bar This her 56 is moved into the path of travel of the roller 160 by the vertical bar during its upward movement, effected by the pattern chain 47, see Fig. 21. t The means for racking the needles are shown in detail, Figs. 4 to 6, applied to the hor ontal needle bed, which for this purdivided. into two parts 162 and 163, .md and guided 0n the stationary bed so as to be free to independently move about the vertical axis of the machine; they ara inrld by screws 16 1 which rest in counte nnk circular slots and are controlled by segn'iental gears 165 and 166 whichmesh 15 into the intcrnal'toothed sections 167 and 168 secured. tothe two parts of the needle bed 162 and 163 respectively. The segment gear 165 is secured to a vertical shaft 169, located in sleeve shaft 170, to the upperjend of i!) which the segmental gear 166 is'secured said sleeve being preferably made in two parts connected by a clutch section 171. Sleeve 17.0 is held in bearings 172, 173 in the interior of the cylindrical needle bed 28, and to 2* end is seeured an arm 17 1, proyided-with a roller 17 5. similar arm 176 witl'x a lfrllfilglfl? is secured to the lower end the shaft 169. 1 7 8 designates a short horizontal shaft liavin g bear i ngs in the standard and in a bracket 179extending inwardlv therefrom. A cam wheel 180 is secured to this shaft near its inner end and alongside this wheel is another cam wheel .l 81. in the coves of these wheels the $5 rollers I75 and 17'? of the arms 174, 176 fit respectively. These cam grooves; are shownat Fig. 6 with three steps reversely arranged.

so that as the cam wheels are intermittently moved the arms 174C and 176 will be rocked in opposite direction--and the segmental goats, connected by the sleeve 170 and shaft 169 to them, will cause the two parts 162 and 163 of the needle bed to move in'oppo site directions. The cam wheels have spaced taper holes 182 in which a locking pin 183 is placed to fasten the cam wheel 181 to 180. Portions of'the cam groove inv wheel 181 may be made with aless or greater number of steps than shown at Fig. 6, and the wheel may be set to bring such portions under roller 177-thus causing the two parts 162, 163 of the needle bed to be differently'racked, or a plain straight part of the cam may be set under the rol er. The part 162 of thebed will then beostationary while the'part 168 is racked. Pattern chain 50 is the'raeking chain and when place'd on the sprocket wheel 7 5 it acts on the roller 184 of a lever 185 rocking on the stud 71. This chain has links of three forms,- the main portion'being of medium height which holds the lever 18.5. in central position, 10w links 186 and high links 187 arranged so as to rock the lever where and .when racking of the needles is desired in knitting a iece of goods. -A link 188 connects the en of lever 185 tofl-one end of a short lever 189 whose shaft 190' has, a bearing in and extends throu h the standard 25, and to. the innerendo this-shafte is secured an arm 191, which by its slotted end and a pin 192 on the 'bar 193, horizontally arranged, causes said bar'to be reciproeated when, the lever 189. is rocked. A link-.194

connects the other end of the short lever. 189

to 'an'arm or lever 195, held to rock on the stud 71, and by a roller 196 is actuated when the chain 50, removed from'the spr0cket 75,

is placed on the sprocket 197. T his sprocket is secured tofthe sleeve 21?, onstud 69, as is.

also the ratchet wheel 76 which is actuated 11o by the pawl '81 carried by the sliding bar 78. See Figs. 22 and 23.. With chain 50. in this polsition the racking bar 193 is, by the mechanism just described, caused to move in the same manner as when the chain is on .the'1 15 sprocket 7 5 actuating the lever 185, and may be so used when it 1s desired to produce a continuousstrip of material, either ribbed or plain, with fancy patterns at intervals throughout its length, the pattern designs 12o i being determined by the art ement. and location of the low andhigh links 186'ai1cl 187 in the chain 50. w p {The connecting mechanism between the rackin bar 193 and camshaft 17 8' comprises a. ratc et wheel 198 having reverse ratchet temps-its opposite sides horizontally arranged, pawls199 and 200 carried'by across head 201 on a vertically--moving bar 202, a

roller on this bar 202-which works in the gromfe o1 a face cam 203 carried on a shaft 201 having hearings in brackets depending from the bed plate 2 -1 of the machine, a. sprocket wheel 205 on this shaft, by a chain 206, receiving motion from the shaft 84, a link 207 being pivotally connected to the pawl 200 and attached to pawl 199 by a slotted connection. The end of the bar acts on a pin 208 projecting from the pawl 200. A spring 209 acts to hold pin 208 against the end of bar 193. A spring 210 is located between the pawls 199 and 200 to causethem to to fas act alternately on the ratchet wheel 198. In

normal inoperative position the arm 191 is vertical, both the pawls 199 and 200 then bein held out of contact with the ratchet whee and consequently do not affect the same although the pawls are continuously moved at regular intervals by the operating parts of the cam 203,-as said cam is continu .ously rotated. This condition exists when the links of the chain 50 of medium height are passing under the roller 184 of the lever 185, of Fig. 23, or under the roller 196 of the lever 195 of Fig. 221 Whenalow link 186 .pases under the rollers the arm 191 moves toward the left in Fig. 5 and toward the right in Figs. 22 and23, allowing the pawl 200 to act onthe ratchet 198, and throu h the medium of cams 180 and 181, cause t e needles to be racked one step for each link of the chain, or two steps when two adjoining links are low links, as shown in Figs. 22 and 23.' Theother pawl 199 is brought into action and ra'cks the needles back to normal position when the high links 187 of.

the chain pass under. the rollers of the levers Of course it will be understood that the number of rackings of the needles and their orderwill be determined by the number of the high and low linksin the 'chain in each group, and the arrangement each revolution of the main controlling parts of the machine. The pawl 80 would there' fore, if uncontrolled, move the chains one link during each forward movement of the bar, and'this would require the use of ve1 y long chains to produce complete fashioned articles of considerable length. To obviate this and enable comparatively short chains to be used, the pawl 80 is permitted to act on the ratchet wheel 72 once only for a given number of rcciprocations of the bar 78, determined by particular requirements of the operation of-the machine. For this purpose a governing chain 51, which may be quite short, is carried by a sprocket Wheel 211 on a sleeve 212 to which is connected the ratchet wheel 76, as is also the sprocket wheel 197; said sleeve being on the stud 69. This chain 51 is of uniform depth except at intervals of a given number, according to its length and required governing power; it has low teeth 213 onto 'which the roller 214 at one end of a lever 215 falls. Lever 21.5. rocks on stud 71 and its other end acts on a projection of a lever 216 pivoted at 217 to a. bearing of the bar 78. This lever .216'is. formcd to extend bencatha pin 218 on the pawl 8Q. Now'when the roller 214 rests on the high main portion of the chain 51,the pawl 80 is raised and held away from the ratchet wheel 72, and when a low part of chain :10 entries under the roller 213 thepawl 80 is released and acts on the ratchet wheel 72 to feedthe pattern chains under their respective levers. The length of the low part of chain 51 or number of links therein is regulated by the number of high and low links in the pattern chains.

\Vhen the chain 50 is used on the sprocket..

wheel 19?, Fig. 22, it may be actuated at intervals in manner similar to its control when on sprocket wheel 75; in this case the pawl 81 is raised and held away from the ratchet wheel 76 by a short lever 219 pivoted at 220 and acting by one of its ends under va pin 221 projectingfrom the side of the pawl, the other end of lever 219 being depressed by the end 222 of the lever 110 when the roller 109 of said lever is moved from a low link to a high link of a governing chain carried by thesprocket wheel 7%..

The separating thread is laid by the eyelet 223 in adjoining courses of the knitting at the j nction of adjoining articles. This eyelet is carried by an arm 224 attached to a block 225- fitted to slide on a circular guideway 226 on the inner side of the ring 32. A lug 227 projects from the outer side of the block-225 arranged in opposition to a plug 228 fitted to slide in a head on'a standard 230, carried by the cam carrier 88 of the cylindrical needle bed of the machine, see Fig. 3. Stem 231 of the plug 228 extends through the head229 and hassecured to its outer end the part of a clutch shaped cam, the counterpart of which is on a ratchet wheel 233 fitted to rotate on the stern 231. This ratchet is actuated by a pawl 234 carried by a slide 235 on the head 229; A lever 236 pivoted at 237 acts by its inner end on the slide 235 and has a roller 238 at its outer end. A spring 239 in the head 229 forces the plug 228 out when the ratchet 233 is moved to let the teeth of the cam clutch 232 enter the spaces between the cam teeth of the ratchet. These parts are similar to and operate in the same manner as the dc vices illustrated in Figs. 17 and 18 for controlling the needle cam 90. The horizontally the separating threads are to be inserted in the-fabric. As the plug 228 is thrown out it contacts with the lug 227 causing the thread carrier 225 to travel with the needle operatmachine; Normally, while-the bod ing cam 90 in laying the thread in a course of stitches in one direction.
